Customer Ratings & Reviews

Amsoil AMO high zinc full synthetic is the recommended oil for my cars engine . The 90-95 Corvette ZR1 needs an oil with the correct additive package of zinc and phosphorus. It's LT5 engine with 4 cams, flat tappets , and 32 valves needs an oil that meets the manufacturers requirements. That oil use to be Mobil 1 full synthetic. Mobile 1 has reduced the zinc and phosphorus package in their current oil. Most new engines have roller valve train and they also reduced the package over catalytic converter life concerns. My engine builder recommends the Amsoil AMO product. It meets the original manufacturer recommendation . I use only Amsoil in all my cars . Especially my Corvette ZR1 with its exotic 528 horse power LT5 . It's cheap insurance .

Running oil in 2 dirt track cars, holds up good under pressure and high rpm’s

I have been using this oil since installing new longblock 25,000 miles ago. I trust my motor to Amsoil.

Hands down best oil. Perfect for my application. I put upwards of 3000 miles a week and I know I don't have to worry about my cam washing out

Have run Amsoil products in all my engines with not one oil related problem in over 30 years.

So far it seems to be working good I’m thinking my old motor has over 300,000 miles on it and it seems to be running more quite then before and good oil pressure. 👍🏻👍🏻

I works good

First time using the product so far so good.

I always try to use Amsoil in my E36 BMW M3. 20w-50 is hard to find and Amsoil has been tested to be the best around.

Great oil. I own a landscape company and We have been using it in all our equipment for years. It has stood up to all the abuses and helped our equipment last longer.

Gives me peace of mind about lubrication of my motor.

I've been using AMSOIL since 2002 starting with my Turbo Hayabusa all the way to current Big Turbo Subaru, this applies to engine, transmission or rear differential. Every time I refresh/rebuild my engine it always looks perfect and shows extremely low to no engine wear on the internals. Pay for the best and get the best!

Amsoil is the only oils I use in our 1982 VW Westfall Vanagon L Campervan

This is an excellent lubricant for motorcycles, as well as autos (JASO MA comp.)

Awesome oil at a great price and very fast shipping!!

A LITTLE PRICEY ,,, BUT IT IS THE BEST ,,,,

2000 miles of hard towing in oil still holding the same pressure and looks as clean as new. Has performed equally well from 80F down to 20F.

Since acquiring my BMW 328iC in 2012, I have been using Amsoil premium products. The car has 167,000 miles on it and looks and runs like new. I also use Amsoil in my work van. Great stuff.

I made the switch to 10w40 Amsoil after installing new longblock. Had been running 5w40 in the last motor. My tuner reccomended this oil after break-in was complete. I trust my EJ255 with Amsoil.
